/**
 * Unit test for dynamic reconfiguration of alternate docroot support.
 *
 * This test configures the virtual server "server" with the following
 * alternate docroot properties:
 *
 * Exact match:
 *
 *   <property
 *     name="alternatedocroot_1"
 *     value="from=/domain.xml dir=${env.S1AS_HOME}/domains/${admin.domain}/config"/>
 *
 * Extension match:
 *
 *   <property
 *     name="alternatedocroot_2"
 *     value="from=*.policy dir=${env.S1AS_HOME}/domains/${admin.domain}/config"/>
 *
 * Path prefix match:
 *
 *   <property
 *     name="alternatedocroot_3"
 *     value="from=/config/* dir=${env.S1AS_HOME}/domains/${admin.domain}"/>
 *
 * and then ensures that a request with a URI of the form
 *   "/domain.xml"
 * is mapped to:
 *   ${env.S1AS_HOME}/domains/${admin.domain}/config/domain.xml
 * (exact match),
 *
 * a second request with a URI of the form
 *   "/server.policy"
 * is mapped to:
 *   ${env.S1AS_HOME}/domains/${admin.domain}/config/server.policy
 * (extension match),
 *
 * and a third request with a URI of the form
 *  "/config/login.conf"
 * is mapped to:
 *   ${env.S1AS_HOME}/domains/${admin.domain}/config/login.conf
 * (path prefix match).
 *
 * If it were not for the alternate docroots, the above requests would
 * result in a 404, since the requested resources are not available in the
 * regular docroot of virtual server "server".
